Our Hermès authentication service pairs a certified expert with a structured, ten-point physical examination of your bag — hardware, stitching, blind stamp, leather grain and documentation — delivered as a digital report within 48 hours. It is the same process professional Hermès authenticators use to clear pieces for resale, insurance and auction.
Whether you need to authenticate Hermès before buying, confirm a Birkin or Kelly ahead of resale, or simply want peace of mind on a vintage find, our reports are built to be accepted wherever proof of authenticity is required.
What Our Experts Examine
Hardware
Weight, plating, engraving depth and screw type — Hermès uses only flathead screws, and hardware feel is one of the fastest tells.
Stitching
The signature saddle stitch: angled, waxed-thread, hand-sewn with consistent spacing that machine stitching cannot replicate.
Blind Stamp
Location, depth and format of the date stamp, cross-checked against the correct pattern for the bag's model and production era.
Leather Grain
Grain pattern, texture and smell specific to each leather type — Togo, Epsom, Clemence and exotics each have a distinct signature.
Documentation
Receipts, prior certificates and provenance where available, weighed alongside the physical examination for a complete verdict.
Frequently Asked Questions
How much does Hermès authentication cost, and how long does it take?+
Expert Physical authentication is €150 with a 48-hour turnaround from photo submission, including a detailed digital report and certificate. An AI Preliminary screening is available for €50 with a 2-hour turnaround for a fast, lower-cost first read.
What photos do I need to submit for authentication?+
Expert Physical authentication requires at least 10 clear photos: the full bag from multiple angles, hardware close-ups, the blind stamp, stitching detail, interior stamps and any accompanying documentation. Sharper, well-lit photos produce a faster, more reliable verdict.
Are your authentication reports accepted by auction houses and resale platforms?+
Yes. Our digital certificates and reports are accepted by major auction houses, resale platforms such as The RealReal, Fashionphile and Vestiaire Collective, and insurers requiring proof of authenticity.
Can you authenticate Birkin, Kelly and vintage Hermès bags?+
Yes. Our experts authenticate Birkin, Kelly, Constance and other Hermès models across every era, including vintage pieces from before 1990, where blind stamp formats and construction details differ from current production.
Is authentication done online, or do I need to send in the bag physically?+
Both our AI Preliminary and Expert Physical services are photo-based and fully remote — you submit high-resolution images through our secure form, and no shipping is required. This gets you a verdict faster than mail-in authentication services.
What happens if my bag is found to be inauthentic?+
You receive a detailed report explaining exactly which discrepancies were found — hardware, stitching, stamps or materials that don't match authentic production. The authentication fee covers our experts' time and analysis and is non-refundable regardless of outcome.
